Seal of Lutellaria / ルテラリアの封印

World. A certain era.
This is the region of Lutellaria, northwest of the kingdom.
Here, long before the history books were written, there was a place surrounded by high walls.
No one knows for what purpose it was erected.
It is hard to get inside the walls, and it is believed that no one ever returned.
It's history within its walls.
